Abstract: A support system includes a plurality of spaced apart cross members, a plurality of decking members supported on the cross members and extending perpendicular to the cross members to form a support surface, and retainers securing the decking members to the cross members. The retainers limit movement of the decking members relative to the cross members in a direction away from the cross members. The cross members, the decking members, and the retainers are formed as separate components. The decking members are secured to the retainers. The retainers are secured to the cross members with a snap fit connection.
